This is introducing many more compiler and linker options than just
frame pointers.
pkg in archive:

At a glance, I see at least:
- new lto flags, like -ffat-lto-objects and -flto=auto
- LDFLAGS was empty before, now it has the mentioned lto changes, and
-Bsymbolic-functions
- -O2 is now used
= FORTIFY_SOURCE=3 is now used
Do we really need all these changes to enable frame pointers? What about
the risk of these other flags being introduced?
